Application filed February 9, 1917. Serial No. 147,593.

To all whom it may concern."

Be it Vknown that I, JOSEPH Il. STENGEL, a citizen of the -UnitedStates, residing at Cincinnati, in the county of Hamilton, State ofOhio, have invented certain new and useful Improvements in TapeGuidesfor Sewingdl/Iachines, of which the following is a description,reference being had to the accompanying drawing and to the figures ofreference marked thereon.

The invention relates to new and useful improvements in tape guides forsewing machines, and more vparticularly to a tape guide which may bereadily adjusted to guide tapes of different widths.

In certain classes of work, it is desirable to stitch simultaneously aplurality of tapes to a fabric, and these tapes are stitched on avmultiple needle stitching machine. An object of the present inventionis, therefore, to provide a tape guide for a multiple needle machine,which tape guide is capable of simultaneously guiding tapes anddirecting the same to the respective needles, and wherein said tapeguide may be quickly adjusted so that all tape guiding sections may besimultaneously varied to the same extent-for a series of tapes of adifferent width.

A further object of the invention is to provide a tape guide for sewingmachines, which tape guide includes a cylindrical member having acircumferential groove of varying width, together with means whereby asection of said groove is made operative for guiding a tape to thestitching mechanism, and wherein the cylindrical member may be adjustedabout its axis to vary the width of the portion presented for guidingthe tape. Y

These and other objects will in part be obvious and will in part behereinafter more fully disclosed.

In the drawings, which show by way of illustration one embodiment of theinvention Figure l is a front view of a portion of a sewing machinehaving my improved tape guide applied thereto;

Fig. 2 is an end view of the same;

Fig. 3 is a view, partly in section and partly in plan, showing a partof the work support and presser foot having my improved tape guide;

Fig. 4 is a vertical sectional View on the line 4--4 of Fig. 3;

Fig. 5 is a bottom plan view of the .presser foot with the tape guidecarried'thereby;

Fig. 6 is a sectional viewthrough the presser foot centrally of the tapeguiding member, showing the tape guiding member for guiding a series oftapes of a given width.

Fig. 7 is a similar view, but showing the tape guiding member adjustedfor guiding a series of tapes of a different width;

Fig. 8 is a sectional view on the line 8-8 of Fig. 6, the tape andfabric being omitted; and

Fig. 9 is a perspective view of the tape guiding member.

In carrying out the invention, I have provided a tape guiding memberwhich is pref erably cylindrical in form and which is provided with aseries of circumferential grooves which extend into the surface of thecylindrical member sul'liciently to form tape guiding walls. Each ofthese circumferential grooves is constructed so that it varies in width,this variation being preferably uniform. The cylindrical member ismounted in the presser foot of the sewing machine in advance of theneedles, and the presser foot is provided with means for directing atape so that a section of the groove becomes effective for guiding thetape which is being stitched. The directing means on the presser foot isof sufficient capacity to take a tape of the Widest width that can beguided by the cylindrical tape guiding member so that this cylindricalmember becomes the active means for guiding the series of tapes to therespective needles. It is often desirable to stitch a series of tapes ofa different vvidth. This may be readily accomplished by adjusting thiscylindrical member so as to present a tape guiding surface which is ofproper width to guide the series of tapes which it is desired to stitchto the fabric. The cylindrical member is for this purpose adjustableabout its axis, and means is provided for holding it in an adjustedposition. Y

Referring more in detail to the drawings I have shown my inventionapplied to a sewing machine which is formed with a work support l, anoverhanging arm 2 carrying a needle bar 3, in which is mounted a seriesof needles 5. As herein shown, there are ve needles. Cooperating witheach neey dle beneath the Work support is a looper Eachneedle andcoperating looper is entirely independent of the other needles andtheircoperating loopcrs. Y

The material is fed across the wor-k support by a feed dog 7 which maybe of the usual construction. The material is held on the Work supportby a presser foot 8 carried 'by ay presser bar 9 mounted in theoverhanging arm 2 in the usual manner. The presser foot is provided witha series of needle openings 10, one foreach needle. The presser foot isalso formed with a slot 11 which extends across the presser foot andWhich is located directly in front of the nee dle openings 10.

Mounted in the slot 11 is a cylindrical tape guiding member 12. Thepresser foot is formed With a raised portion 13 at one side thereof, anda supporting pivot screw 14 extends through this raised portion and isthreaded centrally into the cylindrical member 12, as clearly shown inFigs. 6 and 7 of the drawings. The other end of the cylindrical memberextends into a socket 15 formed 'in the raised portion 16 of the presserfoot. A set-screw 17 carried by this raised portion 16 is adapted toclamp the cylindrical portion and hold it in an adjusted position.Saidcylindrical portion 12 is formed with a slot 18 for a screw-driverto facilitate the adjustment of the same.

This cylindrical member 12 is formed With circumferential grooves 19.There are five grooves, one for each tape. These grooves are of similarconstruction, and only one groove will, therefore, be described 1n detail. The groove extends into the cylindri- .cal member so as to formside Walls 20 and 21. The groove varies in Width. Extendinglongitudinally of the member 12 is a groove 22, and the groove 19extends into f this longitudinal groove 22. The maximum v and minimumWidths referred to.

Width of the groove 19 is at one side of the groove 22, While theminimum Width is at the other side thereof, and the groove variesuniformly in Width between the maximum The presser foot carries a plate23, Which extends from end to end thereof in front of the cylindricalmember 12, and this plate is formed with spaced guiding yrecesses 24,one for each groove 19, and the Width of each recess 24 is the maximumWidth of the groove With Which it cooperates.

In Fig. 3 of the drawings, I have shown a series of tapes, indicated atT. Each tape is directed through a recess 24, and then which issubstantially on the under face of the cylindrical member 12. The member12 is turned until the section of the groove presented for guidingl thetape is of the Width of the tape, and the tapes led in through therecesses 2.4 will be properly directed by the grooves 19 so that theneedles Will form a line of stitching centrally through the respectivetapes.

, Vhen it is desired to change to a series of tapes of different widths,the member 12 is turned until the section of the groove is brought intotape guiding position which is of the Width of the tape desired to bestitched. It will be noted that all the grooves Will be simultaneouslyadjusted so that the operator may go quickly from a series of tapes ofone size to a series of tapes of a different size. It will also be notedthat the tape guide is mounted on the presser foot and is raised andlowered therewith, which greatly facilitates the insertion of thematerial miderneath the same and the removal of the material after thetapes are stitched thereto.

It is obvious that minor changes in the departs may be made, whendesired, Without departing from the spirit of this invention, as setforth in the appended claims.

Having thus described the invention, what is claimed as new is 1. Thecombination with a multiple needle stitching mechanism, of a series oftape guides for independently guiding tapes to the stitching mechanism,and means for simultaneously varying the capacity of the several tapeguides.

2. The combination of a multiple needle stitching mechanism, a presserfoot, a series of tape guides mounted on the presser foot forindependently guiding tapes to the stitching mechanism, and means forsimultaneously varying the capacity of the several tape guides.

3. The combination With a multiple stitching mechanism, of a presserfoot having tape guiding recesses, a series of tape guides for receivingthe tape from said recesses and for directing the same to the needles ofthe stitching mechanism, and means for simultaneously varying thecapacity of the several tape guides.

4. The combination with a multiple stitching mechanism, of a presserfoot having a series of tape guiding recesses, a cylindrical memberhaving a series of circumferential grooves adapted to receive the tapesfrom said recesses respectively and for guiding the tapes to the needlesof the stitching mechanism, said grooves being of varying Width, andmeans for adjusting the cylindrical member for presenting different tapeguiding sections of the groove into operative relation with said guidingrecesses.

5. A tape guide comprising a cylindrical guiding member having a tapeguiding groove extending circumferentially about the same, said groovebeing of varying Width, means coperating with said member whereby aportion of said groove may be utilized for guiding a tape, means forsup- "porting said member, and means whereby said member may be turnedaboutits center axis for varying the Width of the portion presented forguiding the tape.

6. A tape guide comprising a cylindrical guiding member having a seriesof spaced tape guiding grooves extending circumferentiaily about thesame, each of said Grooves being of similar construction and o? varyingWidth, means cooperating With said member whereby the same correspondingportion of each groove may be utilized to guide tapes of the same Width,means for supporting said member, and means Whereby said member may beturned about a central axis for adjusting the same to receive a seriesof tapes of diii'erent width.
